Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to skid plate devices for motorcycles and the like.

(Prior Art) In motorcycles, skid plates are sometimes installed to prevent the lower front and lower part of the engine from directly hitting rocks, etc., and are mainly installed in off-road and racing motorcycles.

(Problems to be solved by the invention) In the above conventional technology, the plate material is pre-molded and connected from below to the lower part of the down tube of the frame and the lower part extending rearward from the lower end of the down tube, and the rock etc. of the engine above is connected from below. It only serves to prevent collisions and has no other functions.

The present invention was developed in view of the above, and its purpose is to utilize skid plates for multiple purposes.
To provide a skid plate device that improves the impact resistance of the skid plate, makes effective use of space, and further lowers the center of gravity of a motorcycle.

(Means for Solving the Problems) A means for solving the above problems is to install skid plates for motorcycles, etc., which are installed to cover the front lower part and lower part of the engine, by inserting the skid plates inside the skid plate. It is formed into a liquid-tight tank shape so that it can contain liquid.

(Effects of the above means) According to the above means, the skid plate is tank-shaped and has a double structure, so it has excellent impact resistance, and can also be used as a storage place for water and fuel, allowing the skid plate to be used for multiple purposes and saving space. It can be used effectively, and since water is stored in the lower part of the engine near the crankcase, the center of gravity can be lowered.

(Embodiment) Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a side view of the motorcycle, Figure 2 is a perspective view of the skid plate, Figure 3 is a plan view of the same, Figure 4 is a side view of the same, and Figure 5 is a sectional view taken along the line 5-5 in Figure 4. , FIG. 6 is a side view of the front part of the frame.

In FIG. 1, a motorcycle 1 supports a front fork 4 that supports a front wheel 3 through a head tube 201 at the front end of a frame 2 in a freely steerable manner, and has a fuel tank 5 on the front of the frame and a fuel tank 5 on the bottom. An engine 6 is mounted thereon, a rear fork 8 supporting a rear wheel 7 is pivotally extended rearward from the rear lower part of the front part of the frame, and a seat 9 is arranged behind the fuel tank 5.

Frame 2 is a head tube 201 in the embodiment.
The left and right main frames 202 extend rearward from the lower part of the head tube 201, one down tube 203 hangs down from the rear upper part of the head tube 201, and the two left and right lower members hang down from the left and right lower parts of the down tube 201 and extend rearward. 204, a vertical rear member 205 that connects the rear end of the lower member 204 and the rear end of the main frame 202, a reinforcing member 206 that connects the rear upper part of the head tube 201 and a cross member horizontally suspended in the middle part of the main frame, left and right rear members 2;
Lateral V-shaped rear stay 2 extending rearward from 05
07, it consists of a seat rail 208 and the like extending rearward from the main frame 202.

A fuel tank 5 is mounted across the main frame 202 of the frame 2, and an engine 6 is mounted below the main frame 202 in a space surrounded by a down tube 203, a lower member 204, and a rear member 205 at the rear. is the first
As shown in FIG.
It is joined to both sides of the lower part 203a of 03, and the front part 204
a is the front end 204b as is clear from the plan view in FIG.
are respectively curved symmetrically toward the lower part of one down tube 203 and joined to the lower part 203a.

The skid plate 10 is disposed so as to cover the lower front part of the engine 6 of the frame 2, that is, the front and lower surfaces of the crankcase 601. The skid plate 10 is as shown in FIGS. 2 to 5, and is composed of a hollow double structure in which a lower plate 101 and an upper plate 102 are joined together, and has a space inside for storing and storing liquid in a liquid-tight manner. The upper plate 102 has a U-shaped recess 104 in plan view, and the front part 10 of the recess 104 has a tank shape.
The lower part 203a of the down tube 203 and the front end 204b of the lower member 204 face 4a, and the recess 1
The front parts 204a, 204a of the left and right lower members 204 face the rear part 104b of the 04. Two openings 105, such as injection ports or discharge ports, are provided in the upwardly protruding portions of the front portions 204a and 204a of the member 204 of the upper plate 102 on the left and right sides, and the front portion 104a of the recessed portion 104 is provided with an outer lower portion. A mounting hole 106 is provided including the joint with the front surface of the plate 101, and mounting pieces 107, 107 are provided on the left and right upper surfaces of the upper plate 102, and the mounting hole 106 is formed by a boss portion protruding toward the front of the lower part of the down tube 203. 203b, and attach the mounting piece 10.
7, 107 are screwed to both left and right sides of the intermediate portion of the crankcase 601 through mounting holes 107a.

In this way, the skid plate 10 is attached to the front surface of the lower part 203a of the down tube 203 and the lower member 204.
It spans over the front lower surface of the engine, and covers the front and lower part of the crankcase 601 of the engine. For example, water is stored in the space 103 of the skid plate 10 and taken out at any time for use as drinking water, or fuel is stored and used as a reserve tank.

Although the above embodiments have been shown for motorcycles, the present invention can also be used for off-road tricycles and the like that employ a similar frame structure.

(Effects of the invention) As is clear from the above, according to the invention, the skid plate for engine guard in motorcycles is shaped like a hollow tank to store and store water, etc., so the skid plate can be used for multiple purposes. Also, since the skid plate can be used to set up a storage tank for water, etc., it is advantageous in terms of space utilization.Secondly, since the skid plate is tank-shaped and has a double structure, it has excellent impact resistance and functions. Furthermore, since a tank containing water or the like is placed below the front of the crankcase at the bottom of the engine, the center of gravity can be lowered.
